Hi @Francesco_Russo , Having SA on client may allow to write backups directly to target S3 endpoint.Eventually, this is to be configured as per your environment and requirements. Thanks,
Hi @Francesco_Russo, RDS Backup: Snapshot + Snapshot Copy to AWS DR Region. For this use case, you may use the common access node / MA with STS assume role configuration. Specify the required account’s (to be protected) STS assume role for the RDS instance configuration in Commvault Command Center.https://documentation.commvault.com/2023e/essential/creating_cloud_database_instance_for_amazon_rds_using_new_aws_account.html Stream based Backup of Oracle/Hana installed locally inside EC2 with CVLT Agent: Primary Copy to local S3 + DASH to AWS DR Region S3 For this use case, each EC2 instance with database to be protected should have the Oracle / Hana Commvault agent installed along with Media Agent / Storage Accelerator package so that the data can directly be written to the S3. This would reduce the hop for data movement from EC2 instance to a common MA and then to cloud library.https://documentation.commvault.com/2023e/essential/oracle_01.htmlhttps://
@Francesco_Russo , if you are planning to use Oracle agent to perform backups, the agent must be installed in the EC2 instance (host) itself. There is no further requirement of access node.https://documentation.commvault.com/2023e/expert/getting_started_with_oracle_agent.html Can you clarify the questions @Chris Hollis asked earlier if the above is not the case.Could you confirm, how are you wanting/planning on doing the backup of the Oracle instance?... is it resident to the EC2 instance VM itself or is it an RDS instance which is independent to any other host runs directly from AWS as an RDS instance?Or are you asking about agentless backup on a VM for oracle instance inside it? Regards,
Hi @MichaelSch , The feature is actively being pursued with development, and not released yet, please contact your account team for further updates. Thanks,
The enhancement would be available in very near term future release.Meanwhile, you can follow the formula for log staging to keep 5 to 15 minutes of logs in CV staging area.
@shailu89 having the local staging directory of decent size on existing discs should do. For example, if you plan to have backup threshold of 20 logs of 4 GB size each, then having 40 logs worth of free space (40*4= 160 GB) should work. Also, the enhancement mentioned above for threshold=1 case is actively being worked upon and is in roadmap. Thanks,
Hi @shailu89 , thanks for reaching out.Are you using log backup threshold as 1?The enhancement mentioned above is specifically to optimize the backup job initialization and is planned for future roadmap. It would be good to have a support case logged so that we can review what might be bottleneck/ issue in your environment. And what are the specific comparison points.
Hi,Having the log staging for 20 logs (around 60 seconds worth in your case) with CV archive log directory on NFS volume, or mirrored disk would reduce the overhead and provide secured archive log storage. Note that this is different than the DB2 online log directory, and thus DB2 server is free from managing the log once its marked as archived. The log is in effect archived immediately and placed in staging location, and then backed up to media when we have 20 logs in staging directory. We do have planned future enhancement in roadmap that would further reduce the per archive log job, stream allocation related tasks involved in direct movement of archive log to backup media. Thank You!
Hi,Looks like currently you have log backup threshold set to 1, which instructs Commvault DB2 vendor agent module to register the job for each DB2 archive log request. You can set the log backup threshold to say 20 ( approximately 3*20 = 60 seconds of transactions taking into consideration that you have one log per 3 seconds). This would average out the overall overhead per log file. The logs would temporarily be staged on the locally mounted Commvault DB2 archive log directory that you had specified during agent install. For information on future enhancement, please contact support.
